The story of Pion comes to an end, so does the story of the Mediators hair.
Pion thanks Mediator for saving her since Mediator turns on the electricity even though Mediator swears she didn't do much. While Pion expresses her gratitude, Mediator asks Pion if she can call her P-girl. She introduces Pion to her assistant and the fairies who have multiplied to three. Later, Pion operates a map, and when Mediator says she is a robot, Pion denies that fact and says she is a human. Then, the room crumbles, and a mysterious man jumps down. Pion thinks the man is Oyage, and the man does not know who he is. He calls himself O-man, and when Mediator says he appears to be malfunctioning, O-man yells at Mediator that he is human. He tells them that he cannot be stopped, and he reveals his bulldozer. During O-man's rant, Pion dives underneath the bulldozer and pushes it back. Though, Pion falls down due to the collapsing ground, and then, everyone else falls down as well. Mediator finds herself in a city with a large lake in the middle. They arrive to the lake where they drink the water. Mediator finds a V badge, and O-man (in a submarine suit) emerges. He summons his slime that makes him transform into a giant cat. When the assistant has his sword and shield, Mediator takes away his equipment. Killer Death Cat (O-man) attacks them. Before O-man slams Mediator with his paw, a nautilus appears and stops the cat.
As the cat beat up the nautilus, some slime fall out, and some fairies emerge from the slime. Pion calls Mediator to lure the cat to her location, so she use a microwave. Mediator asks the fairy to help her, and when the fairy says throw him, she throws him into the nautilus. The nautilus attacks the cat, and Mediator calls Pion to activate the microwave. O-man finds himself and his cat vaporized. When O-man refuses to surrender, Pion delivers a powerful kick. As O-man thrashes around, Pion explains that the microwaves has activated his self restoring ability which restores O-man's memories. Pion admits she is not human. Taking the elevator to the outside world, Grandpa picks up Mediator and her gang.
Later, Mediator and Pion talk with O-man, and the Mediator reveals the true names for Pion and Oyage. Pion's name is "Pioneer" while Oyage is "Voyager." It turns out that these space probes had become more human, and Oyage states that he didn't want to go in space since there was nothing there. Oyage admits that he return to Earth and that he has abandoned his mission. Oyage asks her why she decelerated and why she chase him. When Pion denies, Oyage states she wanted to go home with him. Pion sheds some tears, and Oyage asks why they continue their mission.
Next day, Mediator holds on to Oyage's V badge because it's better that his name stays as Oyage. Grandpa appears and asks Mediator if she sabotage the generator. When Grandpa finds out Mediator did it, he punishes her by having Mediator's hair cut short.
